coupling and adj Listing device for connecting C is the con veyer-box, arranged in the lower the two boards or slides of each pair of cantpart of the casingAand fixed orsecured in any boards orslides; further, inthe novel construcpreferred way to the horizontal bars a. of the tion of the cut-off, and in the combination and casing or frame, one of which bars a is shown roo 5o arrangement of parts, as will be hereinafter in the end view, Fig. I, of the drawings. This fully described and claimed. Y box is divided into two compartments C C2 by a vertical partition c, situated in the vertical center of the bolt in a line drawnvertically through the axis ot' the reel B and the casing, and in the compartments C' C2 are the screw-conveyers D D', one for conveying the iirst grade of flour to the desired place for storage or packing and the other for transferring the second grade of flour to the desired point for subsequent treatment, if deemed necessaryhor desirable. The two conveyers may be driven by a common sprocketchain, (indicated by dotted lines in Fig. I,) which passes around sprocket-wheels on the conveyer-shafts and the reel-shaft.

E F are the series of cantlboards consti tuting the cut-off of my improved bolt, and the cant-boards of the series E are arranged on one side of a vertical line drawn through the reel and partition c, while the boards comprising the other series F are on the opposite side of the imaginary vertical line aforesaid, the two cant-boards being rever'sely inclined to make the lower part of the bolting-chamber substantially V shape in cross-section.

On each side of bolt casing or frame A, I provide a pair of spaced guide-boards G G' and H H', one pair being one side of the casing and the other pair on the opposite side. Each pair of guide-boards extends longitudinally of the casing in juxtaposition to the bars a thereof, and said pairs of guide-boards are connected with the conveyer-box C by vertically-inclined strips I I', which extend from the guide-boards to the vertical partition c in said conveyer-box. These two series of vertically-inclined strips and the two pairs of guide-boards constitute a skeleton-shaped frame for supporting the cant-boards and guiding them in their adjustments, and said strips and guide-boards are inclined to correspond with the angle of the diverging cantboards. The vertically-inclined strips of each series are spaced apart a suitable distance from each other to accommodate the cantboards, and the guide-boards of each pair are arranged the proper distance from each other to leave an intervening space j' into which the cant-boards are fitted or are adapted to fit.

The guide-boards and vertically-inclined strips comprising the skeleton-shaped frame are firmly fastened together by screws or in any other suitable manner, and after the boards and strips have been placed in the casing the conveyer-box is adjusted so that the lower ends of the vertically-inclined strips rest in a V-shaped groove c', cut in the upper edge of the vertical partition c, after which the conveyer-box is rigidly bolted or otherwise secured to the frame or casing, whereby the sides of the skeleton frame are clamped or held in place between the conveyer-box and the casing without the employment of fastening appliances to secure the skeleton frame to the casing.

The cant-boards are tted snugly between the opposing edges of the vertically-inclined strips of the skeleton frame, and to sustain the cant-boards in position, and at the same time secure a close joint between the strips and cant-boards, and to permit the boards to slide a limited distance between the strips, I connect the cant-boards and strips by tongueand-groove joints K, as shown more clearly in Fig. II. The inclined cant-boards of the two series of boards diverge outwardly from the Vertical central partition 'c of the couveyerbox, so that the compartments C C2 of said box lie outside of and below the lower ends of the cant-boards, and the upper side of said compartments in the conveyer-box are closed by means of doors or flaps L L', which are hinged at their inner upper edges to battens or strips Z, rigidly fastened to the inclined strips or bars I I of the skeleton frame at lines above the uppermost limit of the lower edges of the cant-boards even when they are raised, whereby the stock or flour can pass into the compartments when the doors are raised. The opposite cant-boards of the two series are coupled in pairs by intermediate devices which insure positive movement in opposite directions to the two boards composing each pair. Thus the cant-board I of the series E is connected to the cantboard 5 of the series F, the cant-board 2 of the series E to the cant-board 6 of the series F, and so on throughout the two series of cant-boards extending the entire length of the reel and casing of the bolt.

The coupling device for each pair of cantboards preferably consists of a bell-crank lever M, arranged transversely in the chamber between the cant-boards, and to the ends of said lever are pivoted the links m m', which have their free ends attached to the opposite cant-boards by the hooks m2, (shown in detail in Fig. V,) said hooks having an eye m3 to receive a screw which fastens it to the cantboard, and the free end of the hook is extended to penetrate or enter the cant-board a short distance to securely fasten the link to the cant-board. The bell-crank lever may be supported in the chamber in either of two ways-first, by pivoting each lever to a flat bar or iron N or fitting the whole series of bell-crank levers loosely on a rod N', which extends longitudinally through the bolt-casing. If the hat bars or irons N are used, they should be fastened to the opposite strips I I of the skeleton frame, and the levers should be pivoted to one side of the bars, so as to be out of line with the bars or strips I I', and thus adapt the links to be properly connected to the cant-boards. If, on the other hand, the single supporting-rod N' is used, the number of bars N can be materially decreased, a number of the bars being spaced at suitable intervals through the length of the bolt to properly support the levers, one of which is connected to each pair of opposite cant-boards.

The cant-boards are each provided on the outside with a knob o to permit the ready IOO IIO

manipulation or adjustment of the board by hand.

In the practical operation of the improved bolt one-half of the boards of one series E, or those which lie below the receiving end of the reel, are lifted, and likewise one-half of the boards of the other series F, or those which lie below thedischarge end of thereel, are likewise lifted, it thus being seen that one-half of each series of cant-boards on opposite sides of the box and at opposite ends of the reels are lifted to provide two series of openings through which the stock or tiour of different grades from both ends of the reel is free to pass into the respective compartments of the box. As the elevated cantboards E below the receiving end of the reel are connected by the levers with the cantboards of the series F below the same end of the reel and on the opposite side of the box, the cant-boards F below said receiving end of the reel are depressed, whereby the firstgrade iiour is directed into the compartment C', and as the elevated cant-boards F below the discharge end of the reel are connected to the cant-boards E below the same end of the reel in like manner by the levers the cantboards E below said discharge end of the reel are lowered to direct the second-grade flour into the openings provided by the elevated boards F to deliver to the compartment C2.

Although I have shown in Fig. II the adjacent cant-boards in different positions for the purpose of illustrating the adjustments, yetI would have it understood that the boards at one end of the bolt should occupy the sanne relative positions-that is, all the cantboards on two sides for one half the length ofthe reel should be lowered and raised, respectively, while all the cant-boards below the other half of 'the reel should in like manner be adjusted in reverse order.

The operation and advantages of my invention'will be readily understood by those skilled in the art to which the improvement relates from the foregoing description, taken in connection with the drawings.

I am aware that changes in the form and proportion of parts and details of construction of the mechanism herein shown anddescribed as an embodiment of. my invention can be made without departing from the spirit or sacrificing the advantages of my invention. I therefore reserve the right to make such modifications as fairly fall within the scope of my invention.
